Kong handed Tsugikuni Yoriichi a dossier on the Beasts Pirates.
Ever since Kaido and King escaped from Tsugikuni Yoriichi's hands, they had entrenched themselves on Risky Red Island, located in the early part of the New World. As mentioned before, the Log Pose on Fish-Man Island pointed toward three islands.
According to the dossier, Risky Red Island was one of the three islands indicated after Fish-Man Island.
Since the Great Pirate Era began, pirates from the Four Blues had flooded into the Grand Line. After reaching the Sabaody Archipelago, they would head to Fish-Man Island, then use it as a stepping stone into the New World.
Risky Red Island was the first stop for many pirates entering the New World.
Kaido's Beasts Pirates were now entrenched on Risky Red Island, "claiming the island as king" and gathering pirates seeking to make their names in the New World, thereby expanding their own strength.
After a period of operation, the Beasts Pirates had grown into an enormous force.
Marine Headquarters had only learned of this some time ago. By chance, the Marines captured the captain of a pirate crew that had withdrawn from the New World and returned to the Sabaody Archipelago.
From him, they learned that Risky Red Island had fallen under the control of the Beasts Pirates.
After receiving this information, Kong had people infiltrate the island by every possible means. Following a period of investigation, they had roughly figured out the situation on the island.
For Kong, Yoriichi's trip to Fish-Man Island was an excellent opportunity.
Marine Headquarters was severely lacking in high-end combat power. Under the current circumstances, the Headquarters' strongest forces were needed to suppress the Four Blues. The Four Blues were the foundation of the Marines, and absolutely could not be allowed to have any problems.
